Authorities in Singapore say they have identified 15 more Zika virus infections that were transmitted locally. That takes the total number of confirmed cases to 56.
The 15 new cases identified are in the same Aljunied and Sims Drive area in the south-east of the island, where authorities had previously identified 41 cases of Zika virus infection. This brings the total number of people who have been locally infected to 56.
Singapore's National Environment Agency has deployed more than 200 people to the affected area, where they sprayed insecticide and cleaned drains.
Meanwhile, the Ministry of Health warns more cases are likely to be uncovered and is advising mothers-to-be to avoid affected areas.
The most vulnerable group of people for Zika are pregnant ladies, as the virus can be dangerous for unborn children. About 1 percent to 13 percent of women infected while pregnant could give birth to babies with smaller heads – a condition known as microcephaly – and other brain defects.
